Set-up instructions
For 4-channel operation, set these two switches to STD (standard).
Connect your 4 input channels using either unbalanced (RCA) or balanced (XLR) cables.
Channels are labeled 1, 2, 3 and 4. Set the four toggle switches to UNBAL (unbalanced) or
BAL (balanced) as appropriate.
Connect your four speakers to the output binding posts: 1, 2, 3 and 4. Speaker wires can
be terminated with “banana plugs” which are inserted, or stripped insulation (unscrew
binding post cap, insert wire into hole on threaded shaft and tighten cap). Observe correct
polarity (“+” red and “-“ black).

The amplifier can be turned-on automatically by, for example, your preamp/processor by
connecting a 12-volt trigger wire to TRIGGER IN. You can use TRIGGER OUT to connect a
“downstream” component such as another amplifier to also be turned-on automatically.
Connect the power cord to AC INPUT and plug the other end into a 120-volt wall socket.
Set the rocker switch to ON to power-on the amplifier.
Your AD4.320 can also serve as a 2-channel or 3-channel amplifier, delivering greater
power to 2, or to 3 channels. This is done by “bridging.” For 2-channel operation, first,
TURN OFF THE AMPLIFIER. Then, set both switches to BRIDGE.
Connect your inputs and outputs to 1 and 3 (INPUTS can be unbalanced RCA or balanced XLR;!
set toggle switches accordingly and use speaker wire for OUTPUTS). Twice the power will be
delivered to OUTPUTS 1 and 3. Only turn on the amp AFTER these changes are made.!
For 3-channel operation, first, TURN OFF THE AMPLIFIER. Then, set one switch (left one in this
example) to BRIDGE. Connect your inputs and outputs to 1, 2 and 3 (INPUTS can be unbalanced
RCA or balanced XLR; set toggle switches accordingly and use speaker wire for OUTPUTS). Twice
the power will be delivered to OUTPUT3. Only turn on the amp AFTER these changes are made.
Operation
Vertical light on the front panel should be green. If it turns yellow, power-off, wait, then restart.
